Introduction
The Czech accident investigation authority (ÚZPLN) investigated a ground collision involving a Piper PA28R-301T Arrow, registration OK-POL, and a Let L-410, registration OK-SAS, at Příbram Airport (LKPM) on 9 March 2014. The accident occurred at approximately 12:25 UTC.
Sequence of Events
The pilot of the PA28R intended to fly from LKPM to Tábor (LKTA) and back. He took over the aircraft, which was positioned on the asphalt apron in front of the hangar, ready for flight. After starting the engine, he increased power. The aircraft began to move and turned left. Before the pilot could react by reducing power, applying right rudder, or braking, the left wing of the PA28R struck the lower right front fuselage of the L-410. The L-410 was parked on an asphalt parking area adjacent to the apron, northwest of the hangar. Its forward part extended approximately 1.5 meters onto the apron.
Aircraft and Personnel
The PA28R was owned by Smooth Sky s.r.o. and operated by SKY Academy s.r.o.; the pilot (a 36-year-old male holding a PPL(A) license with 132 total hours) had rented it. The L-410 was owned by KJ Support s.r.o. and operated by Skydive Air Service s.r.o. Both aircraft were undamaged beyond the PA28R's left wing damage and minor scratches on the L-410's fuselage. The crews of both aircraft were uninjured. A breathalyzer test administered to the PA28R pilot was negative.
Weather and Airport
Weather conditions were CAVOK with light haze near the surface, visibility 10 km or more, and wind variable up to 4 knots. The AFIS station at LKPM was not in operation at the time, as it was outside published operating hours. The airport is a public domestic aerodrome; no taxiway system was published in the AIP for LKPM. The centerline of the asphalt apron was marked with yellow paint.
Conclusion and Cause
The investigation concluded that the cause of the accident was the collision of the taxiing PA28R with the stationary L-410, caused by the pilot's failure to comply with general air traffic regulations as specified in Regulation L2, Head 2 (2.2, 2.3, 2.3.1) and Head 3 (3.1.1, 3.2.5). Specifically, the pilot did not maintain adequate distance from obstacles during taxi and did not react in time to correct the aircraft's direction or stop. No safety recommendations were issued by the investigation authority.
